Dr. Will Morris has rehabbed a lot of injuries; I'm using his protocol to rehab mine right now and it's working splendidly. He's not a regurgitator of textbooks; rather he's one of the best pro-barbell PTs in the field. I'm not sure why he busted your balls so hard (just skimmed it). Got up on the wrong side of the bed? Both he and I come from a martial tradition that hazes their members pretty hard, so I'd guess it's more likely run-of-the-mill hazing with some hidden advice in it.
I see he referred you to at least one article on back rehab which may be tangentially applicable to you; I marked that for later reading tonight. Did you give it a look?
